Recently, Anti-Fraud has received numerous reports about applications capable of impersonating phone numbers. In fact, this isn&#039;t a new trick, but rather a technique for spoofing displayed phone numbers, also known as phone number spoofing. <strong><a href=\"https:\/\/en.wikipedia.org\/wiki\/Caller_ID_spoofing\" target=\"_blank\" rel=\"noreferrer noopener\">Caller ID Spoofing<\/a><\/strong>, which has been around for many years.<\/p>\n\n\n\n<p>Let&#039;s go together <strong><a href=\"http:\/\/chongluadao.vn\/blog\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">Anti-Phishing<\/a><\/strong> Learn about this technique and how to protect yourself from related scams.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Overview of Caller ID Spoofing<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1.1. This technique is not new and has a history of over 20 years.<\/h3>\n\n\n\n<p>Caller ID spoofing is not an invention of the smartphone age or of today&#039;s scam groups. This technique has existed for a long time, initially in the hands of those with specialized connections to telecommunications exchanges. The first publicly available Caller ID spoofing service launched in the US on September 1, 2004, allowing for fraudulent calls to be made directly from a web interface, without the need for specialized equipment.<\/p>\n\n\n\n<p>The technical barriers have only gotten lower since then. The key factor that has made this technique dangerous and widespread over time is the rise of... <a href=\"https:\/\/en.wikipedia.org\/wiki\/Voice_over_IP\" target=\"_blank\" rel=\"noopener\"><strong>VoIP<\/strong><\/a> (Voice over Internet Protocol) is a technology for transmitting voice over the Internet. Previously, spoofing numbers required in-depth knowledge of telecommunications equipment and was expensive. But with the popularity of VoIP and open-source software, today anyone can do it with minimal cost and effort.<\/p>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61, .wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61[data-kb-block=\"kb-adv-heading5851_315372-61\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61[data-kb-block=\"kb-adv-heading5851_315372-61\"] mark.kt-highlight{font-style:normal;color:#ff0019;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading5851_315372-61[data-kb-block=\"kb-adv-heading5851_315372-61\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<p class=\"kt-adv-heading5851_315372-61 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading5851_315372-61\">Over the past two decades, this technique has been documented in countless global scams, ranging from impersonating police officers, utility companies, and immigration officials, to impersonating relatives to request urgent money transfers. To the point that in 2019, the US AARP organization issued a warning:\u201c<strong><mark true=\"true\" class=\"kt-highlight\">You can no longer trust the numbers displayed on the screen.<\/mark><\/strong>\u201c&quot;\u201c<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1.2. The Technical Nature of Caller ID Spoofing<\/h3>\n\n\n\n<p>Since 2021, experts at Anti-Fraud have conducted in-depth research on this technique across several Internet Voice over IP (VoIP) services, digital PBX systems, and cloud calling services. At that time, due to its dangerous nature, the technical details were kept confidential to prevent exploitation by malicious actors.<\/p>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4, .wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4[data-kb-block=\"kb-adv-heading5851_01f20e-d4\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4[data-kb-block=\"kb-adv-heading5851_01f20e-d4\"] mark.kt-highlight{font-style:normal;color:#fd0115;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading5851_01f20e-d4[data-kb-block=\"kb-adv-heading5851_01f20e-d4\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<p class=\"kt-adv-heading5851_01f20e-d4 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading5851_01f20e-d4\">Regarding Caller ID spoofing, in short, it means the caller doesn&#039;t necessarily use their real number when making a call, but the recipient&#039;s phone can still display a different number on the screen. In other words, <strong><mark true=\"true\" class=\"kt-highlight\">The number you see on the screen may not be the actual number calling.<\/mark><\/strong>.<\/p>\n\n\n\n<p>Technically speaking, a phone call isn&#039;t as simple as we think. It&#039;s divided into two separate parts: <strong>Actual route<\/strong> of calls within the telecommunications network and <strong>Information displayed<\/strong> For the recipient.<\/p>\n\n\n\n<p>The difference lies here:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Number used in the network:<\/strong> It is the actual identity of the caller that the network operator connects them to.<\/li>\n\n\n\n<li><strong>Display Number:<\/strong> This is the information sent along with the message to be displayed on the recipient&#039;s phone screen.<\/li>\n<\/ul>\n\n\n\n<p>Through intermediary systems like VoIP, fraudsters can easily alter the displayed data fields.
